OOPs concepts and difference between abstraction vs encapsulation

Question

Accepted Answer

Abstraction focuses on what an object does, while encapsulation focuses on how it does it.

Abstraction is the process of hiding complex implementation details and showing only the necessary information to the user.
Encapsulation is the process of wrapping data and methods into a single unit, preventing direct access to the data from outside the unit.
Abstraction is achieved through abstract classes and interfaces.
Encapsulation is achieved through access modifiers like public, private, and protected.
Abstraction is a higher-level concept than encapsulation.
Example of abstraction: A car's dashboard shows only the necessary information to the driver, like speed, fuel level, and temperature.
Example of encapsulation: A bank account's balance is encapsulated and can only be accessed through methods like deposit and withdraw.
